2009-01-09When we see a reference to a struct, class, or union like "struct X"Douglas Gregor
that is neither a definition nor a forward declaration and where X has not yet been declared as a tag, introduce a declaration into the appropriate scope (which is likely *not* to be the current scope). The rules for the placement of the declaration differ slightly in C and C++, so we implement both and test the various corner cases. This implementation isn't 100% correct due to some lingering issues with the function prototype scope (for a function parameter list) not being the same scope as the scope of the function definition. Testcase is FIXME'd; this probably isn't an important issue. Addresses <rdar://problem/6484805>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62014 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-06rename MaybeParseCXXScopeSpecifier -> ParseOptionalCXXScopeSpecifier and Chris Lattner

2009-01-06rename tok::annot_qualtypename -> tok::annot_typename, which is bothChris Lattner
shorter and more accurate. The type name might not be qualified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61788 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05remove optimization to avoid looking ahead for cases like ::foo. ThisChris Lattner
isn't worth the complexity and the code already does a ton of lookahead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61671 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05Rearrange some code in TryAnnotateTypeOrScopeToken to make it Chris Lattner
early exit for C and avoid template lookup for C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61667 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05TryAnnotateTypeOrScopeToken and TryAnnotateCXXScopeToken can Chris Lattner
only be called when they might be needed now, so make them assert that their current token is :: or identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61662 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-05ParseCXXSimpleTypeSpecifier can only be called on things that areChris Lattner
verified to be simple type specifiers, so there is no need for it to call TryAnnotateTypeOrScopeToken. Make MaybeParseCXXScopeSpecifier reject ::new and ::delete with a hard error now that it may never be transitively called in a context where these are legal. This allows me to start disentangling things more. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61659 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-04my previous patch caused sema to drop the global qualifier, makeChris Lattner
sure to pass it down. This makes the code a bit gross, I will clean it up in subsequent commits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61650 91177308-0d34-0410-b5e6-96231b3b80d8

become useful or correct until we (1) parse template arguments correctly, (2) have some way to turn template-ids into types, declarators, etc., and (3) have a real representation of templates. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61208 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-08Fix PR3172: if we see an eof or } at the top level, reject it.Chris Lattner
This is important because ParseDeclarationOrFunctionDefinition skips to, but does not consume, an } on error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60719 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-22Split the DiagnosticInfo class into two disjoint classes:Chris Lattner
one for building up the diagnostic that is in flight (DiagnosticBuilder) and one for pulling structured information out of the diagnostic when formatting and presenting it. There is no functionality change with this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59849 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-18remove the last couple obsolete forms of Parser::Diag.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59510 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Change a couple of the Parser::Diag methods to return DiagnosticInfoChris Lattner
and let the clients push whatever they want into the DiagnosticInfo instead of hard coding a few forms. Also switch various clients to use Diag(Tok, ...) instead of Diag(Tok.getLocation(), ...) as the canonical form to simplify the code a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59509 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18This reworks some of the Diagnostic interfaces a bit to change how diagnosticsChris Lattner
are formed. In particular, a diagnostic with all its strings and ranges is now packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a ton of random stuff. This has the benefit of simplifying the interface, making it more extensible, and allowing us to do more checking for things like access past the end of the various arrays passed in. In addition to introducing DiagnosticInfo, this also substantially changes how Diagnostic::Report works. Instead of being passed in all of the info required to issue a diagnostic, Report now takes only the required info (a location and ID) and returns a fresh DiagnosticInfo *by value*. The caller is then free to stuff strings and ranges into the DiagnosticInfo with the << operator. When the dtor runs on the DiagnosticInfo object (which should happen at the end of the statement), the diagnostic is actually emitted with all of the accumulated information. This is a somewhat tricky dance, but it means that the accumulated DiagnosticInfo is allowed to keep pointers to other expression temporaries without those pointers getting invalidated. This is just the minimal change to get this stuff working, but this will allow us to eliminate the zillions of variant "Diag" methods scattered throughout (e.g.) sema. For example, instead of calling: Diag(BuiltinLoc, diag::err_overload_no_match, typeNames, SourceRange(BuiltinLoc, RParenLoc)); We will soon be able to just do: Diag(BuiltinLoc, diag::err_overload_no_match) << typeNames << SourceRange(BuiltinLoc, RParenLoc)); This scales better to support arbitrary types being passed in (not just strings) in a type-safe way. Go operator overloading?! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59502 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-18Change the diagnostics interface to take an array of pointers to Chris Lattner
strings instead of array of strings. This reduces string copying in some not-very-important cases, but paves the way for future improvements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59494 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Eliminate all of the placeholder identifiers used for constructors,Douglas Gregor
destructors, and conversion functions. The placeholders were used to work around the fact that the parser and some of Sema really wanted declarators to have simple identifiers; now, the code that deals with declarators will use DeclarationNames. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59469 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-08Implement support for C++ nested-name-specifiers ('foo::bar::x') in the ↵Argyrios Kyrtzidis
Parser side. No Sema functionality change, just the signatures of the Action/Sema methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58913 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-06Implement support for C++ direct initializers in declarations, e.g. "int x(1);".Argyrios Kyrtzidis
This is how this kind of initializers appear in the AST: -The Init expression of the VarDecl is a functional type construction (of the VarDecl's type). -The new VarDecl::hasCXXDirectInitializer() returns true. e.g, for "int x(1);": -VarDecl 'x' has Init with expression "int(1)" (CXXFunctionalCastExpr). -hasCXXDirectInitializer() of VarDecl 'x' returns true. A major benefit is that clients that don't particularly care about which exactly form was the initializer can handle both cases without special case code. Note that codegening works now for "int x(1);" without any changes to CodeGen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57178 91177308-0d34-0410-b5e6-96231b3b80d8
